UNITED STATES WILLIAM T. IVINS, OF HAMILTON, OHIO.

LINER Application filed September 30, 1922. Serial no. 591,592.

To all whom it may concern:

Be it known that 1, WILLIAM T. lviNs, a citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented new and useful Improvements in Liners, of which the followin is a specification.

Iy invention relates to improvements in machines of the class known as linotype or line-casting machines, in which lines of matrices are assembled and the metal afterward cast against them to form a complete line of type.

My invention specifically resides in the means for adjusting at one time and with one change the length or thickness of the line to be cast by a small change in what is termed the liner.

An object of the invention is to provide means by which skeleton slugs of different lengths can be produced without the necessity of using lines of special form.

Another object being to provide a device by means of which a skeleton slug having a thin portion in its body and a wide face can be cast of any desired length by use of my integral liner, and the ribs thereon varied in width to comply with thediiferent measurements.

Referring to the accompanying drawings:

Figure 1. is a front view of a mold having my liner applied therein.

Figure 2 is a rear elevation of the same.

Figure 3 is a perspective view of the liner.

Figure 4- is a bottom plan of the liner and Figure 5 is a perspective view of the slug produced.

In the drawings 1 represents the body portion of themold presenting a flat upper surface; 2 the cap portion overlying the body and presenting an under surface parallel with the top surface of the body. Arranged between the cap and body members, is the liner 3 consisting of a plate of metal with its thickened ends 4 extended and confined between the cap and body, so that the under side of the line forms the top of the mold cell or slot. The underside of the liner is formed with downwardly extending projections or bosses 5 to form the cavities or recesses in the slug. It will be observed that these projections 5 vary in width and extend to the rear face of the mold, but the front faces terminate in the rear of the front face 6, in order that the front edge of the slug is cast of full thickness. The projections of the latter are separated by transverse grooves 7 which form upon the slug corresponding ribs 7 standing out from the body comparatively flush with the front edge to give the type-face the requisite support and to permit contact against the adjacent slug in the form. By having the projections 5 of varied widths the ribs of the slugs are so disposed and in the drawings the ribs areshown as spaced to come within 4: picas, '12 picas, 12 picas and 13 picas, thereby do ing away with the necessity of using lines of a special form. The ends 4i of the liner are preferably notched as shown 8, in order that they may be retained in place by the usual end bars or gibs which. connect the cap and body.

The length of the slug produced in the mold is varied by inserting the usual filler pieces and the thickness of the slug is varied by changing the liner. The end portions 4 being of various thicknesses thereby eliminating the end filling liners.

No limitation is implied by reason of the particular form shown, but various modifications may be made within the scope of the invention as defined in the following claim.

What I claim as my invention is:

A slug producing liner: of the character described comprising an integral elongated strip, thickened ends formed on the strip and being provided with notches extending from one side edge and terminating beyond the middle thereof, a plurality of projections of varied widths arranged between the thickened ends and being separated through the medium of transverse grooves, and said projections forming straight side walls for the grooves and thereby providing corresponding ribs upon the slugs as and for the purpose specified.

In testimony whereof I affix my signature.

WILLIAM T. IVINS.
